When was the last time your building’s air ducts were professionally cleaned? For businesses, indoor air quality directly affects employee health, HVAC efficiency, and compliance with safety regulations. In this post, we break down what to expect during a commercial air duct cleaning service—so you can be prepared, informed, and confident in your investment.
1. Initial Inspection & Site Assessment
Before any equipment comes in, a trained technician will perform:
A walkthrough of the facility to assess duct layout and access points.
Inspection of HVAC components, including air handlers, coils, registers, and vents.
Use of cameras or scopes to inspect inside ductwork for dust, debris, mold, or damage.
A custom cleaning plan based on building size, duct condition, and business hours.
???? Tip: Choose a provider that complies with NADCA (National Air Duct Cleaners Association) standards.
